Minutes/Action items of "Instrumentation-Systems-SDA" monthly meeting October 3, 2007 ------------------------------------------------------------------------- Present: J. Annala, M. Convery, C. Gattuso, I. Kourbanis, A. Lumpkin, C. McClure, T. Meyer, V. Papadimitriou, J. Patrick, S. Pruss, D. Slimmer, R. Thurman-Keup, A. Tollestrup, D. Voy, M. Wendt, J. Zagel We discussed the following: -------------------------- 1) Main Injector FW measurement of beam sent back from the Tevatron during reverse injection cycles Jim Zagel 2) Flying Wire RFT status Craig McClure 3) Status of Longitudinal emittance algorithm updates for MI. How will we commission the new algorithm? Alvin Tollestrup - Part I Randy Thurman-Keup - Part II 4) Updated bunch by bunch emittance and intensity tables Timofei Bolshakov, Vaia Papadimitriou ------------------------------------------------------------------------------------ Conclusions-Action Items: 1) It looks like we will be able to perform regularly and reliably the measurement of beam sent back from the Tevatron during reverse injection cycles with the MI flying wires after some changes in the triggering of Fly spec 24 and determination of some needed delays. Some of the needed information will be obtained during commissioning in a couple of weeks. 2) VME RFT status: a) The socketed hysteresis setting resistors in the VRFTs will be soldered instead, to minimize erratic behavior. To start with, this will be done in the VRFT of MI FW system. b) There is a new VRFT design which is expected to have broader functionality. The lack of VRFT spares for our current system will be addressed by expediting the new VRFT design to include the current functionality only for some of the modules to be produced. 3) It looks like we are on track on having available an improved Main Injector longitudinal emittance algorithm (similar to the Tevatron algorithm) by the end of the shutdown. this will provide a 95% longitudinal emittance for MI. We will still start up with the old system which will make scope data available as well to the new system so that we can perform comparisons of the two systems with the same data. When the commissioning is complete, we will switch to the new system. 4) There are updated bunch by bunch emittance and intensity tables available from the SDA page (http://www-bd.fnal.gov/SDA_Viewer/bunch_by_bunch_catalog.jsp). These tables can be built at will but they will start being built automatically as we get new stores. HTML, excel and stucture versions are available. We encourage the Systems groups to start using these tables and give us feedback. Our next meeting is scheduled for November 7, 2007.
